AI and accelerated computing are reshaping expectations for data center infrastructure, and that shift is especially visible inside carrier hotel environments. Research from McKinsey notes that average rack power densities have more than doubled in two years, rising from 8 kilowatts to 17 kilowatts, with projections reaching 30 kilowatts per rack by 2027. Carrier hotels have long served as central meeting points for carriers, content providers, and enterprises, delivering dense interconnection in the heart of major metros. As fifteenfortyseven Critical Systems Realty (1547) has outlined in its connectivity hubs blog, these buildings keep communities and businesses online by concentrating networks and cloud on-ramps in a single, neutral location. For 1547, the focus is evolving these hubs to host modern AI workloads without compromising the connectivity advantages that make them essential.
A Shifting Infrastructure Reality
Carrier hotels were not originally built for AI. Historically, these facilities centered on abundant fiber, building-level power resilience, and space for many carriers to interconnect, with typical cabinet deployments remaining within just a few kilowatts. Dgtl Infra describes carrier hotels as highly interconnected urban facilities where carriers, cloud providers, and enterprises converge to exchange traffic and access key services. Modern GPU-based systems have pushed power density requirements into the tens of kilowatts, with infrastructure manufacturers such as Vertiv pointing to configurations exceeding 100 kilowatts per rack in advanced AI and high-performance computing environments. Instead of asking how much floor space is available, customers now want to know how much usable power can be delivered to each rack and how the facility will manage the resulting heat.
Why Increasing Power Density Creates Unique Challenges for Carrier Hotels
The same characteristics that define carrier hotels also introduce constraints that greenfield campuses do not face. Many occupy historic or mixed-use buildings in dense metro cores, where increasing utility capacity requires coordination with local utilities, municipalities, and building ownership. 1547’s Pittock Block in Portland illustrates this directly, with a century-old downtown landmark transformed into a modern carrier hotel and data center. Cooling presents a parallel challenge. Traditional air-cooled systems adequate for network gear and standard compute begin to struggle as rack densities climb, and McKinsey projects a potential supply deficit by 2030, driven by AI-ready capacity requirements that current infrastructure was not designed to meet.
